CIGAR-BU'NCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 416,666, dated December 3, 1889.

Application filed June 30, 1884. Serial No. 136,454. (No model.) i i To all whom it may concern:

Be it known that I, RICHARD A. BRIGHT, of Providence, in the State of Rhode Island, have invented an Improvement in Cigar- Bunching Machines, of which the following is a specification.

The nature of myinvention consists in the improved combination of feeding devices whereby a uniform sheet of fillers will be formed, and also in improved devices for receiving the filler when separated from the sheet and depositing the same in the rollingchamber of the binding mechanism.

Figure 1 is a perspective view of the complete machine. Fig. 2 is avertical section of the feeding portion of the machine. Fig. 3 is a bottom view of a portion of the filler receiving and depositing mechanism. Fig. 4 is a section taken in the line a: :r of Fig. 3. Fig. 5 is a transverse section taken in the line y of Fig. 3. Fig. 6- is a detail section showing the projecting lip adapted to hold back the spring-jaw of the receiving-chamber. Fig. 7 is a detail section showing the filler-chamber when in its receiving position. Fig. 8 is a similar section showing the relative position of the parts when depositing the filler in the rolling-chamber. Figs. 9, 10, 11, and 12 are detail views. I

In the accompanying drawings, Fig. 2, A is the frame of the machine; B, the endless feeding-apron upon which the loose tobacco is first deposited in depth equal to the height of the upright parallel guides C, between which the upper portion of the apron B is made to run, and an inclined scraper a is provided for removing dust from the inner surface of the apron in order to prevent slipping on the rolls D D. At a suitable distance above the roll D is placed the roll D which is adapted to even off the mass of fillers placed upon the apron B. Below the plane'of the feeding-apron B is arranged the carrying-apron E, which passes over the rolls F F, and the forward portion of the apron is supported against a downward pressure by means of the intermediate rolls F F F The revolving brush G is arranged obliquely across the inner side of the lower portion of dust or scraps of tobacco, which, if not removed, would tend to cause the apron to slip on the rolls F F. Above the forward end of the apron E is placed the endless apron II, passing around the forward roll I and the larger rear roll I, and the tightening-roll I is made to bear upon the upper side of the apron H, thus serving to insure a positive motion to the apron H for feeding the loose tobacco forward between the two aprons H and E, and the aprons H and E are made to converge toward each other in a forward direction in order to properly compress the loose tobacco into a sheet suitable for entrance into' the filler-receiving chamber.

Between the forward portion of the apron B and the rear portion of the apron E is placed the guide-plate J, in front of which is arranged the spur-roll K, which serves to rearrange the loose tobacco upon the apron E as it is received from the apron B. The spurroll K, which extends across the machine above the bed, may be formed of a cylinder having its periphery set with projecting pins or spurs 19 Fig. 11, and is operated by means of the pawl a, Fig. 1, and ratchet-wheel b, from. which operative connection is made to the cam L upon the shaft 0 by means of the shaft 6, with its attached arms f and g, connecting-bar h, and the vibrating arm 1;, secured to the end of the shaft j of the spurroll; and the feeding-belt B is driven by means of a pawl 01, and the ratchet-wheel c operated from the cam L by means of the arm 70, secured to the rocking shaft e, connectnecting-arms or the resilient force of an equivalent spring.

The aprons E and H are driven by means of the ratchet-wheel H upon the shaft of the roll F and the connected gears, as shown in Fig. 9, the gears n and 0" serving to drive rocking arm (1, connecting-lever d rocking the apron E in order to clear the apron from the roll I from the shaft i of the roll F, the :00

rolls F F F being also driven in the same direction by means of the gears q, s, and 16 upon the shafts of the respective rolls and the intermediate gears p, r, and u, and the roll I is driven from the intermediate gear a by means of the gear n upon the shaft of the roll and the intermediate gear 6 the ratchet 2 being operated from the shaft tby means of the cam J, pivoted arm K, and connecting-rod L.

The knife M, which serves to divide the filler in the receiving-chamber N from the forward-moving sheet of tobacco between the aprons E and H, is secured to the sliding head 0, to which an up-and-down movement'is imparted in timely relation to the opening and closing movement of the rolls of the binding mechanism by means of the cam Q upon the shaft t, loose bell-crank arm .2 upon the rod 8, connecting-rod '6, arm j upon the rocking shaft segment gear Z, and rack m, attached to the sliding head.

The brush G, which serves to clear the dustand fine tobacco from the lower portion of the apron E, may either have an intermittent movement by band-connection with the shaft of the driving-roll of the apron E or it may have a continuous rotary movement in a direction contrary to the movement of the apron by means of band-connection with the driving-shaft of the machine, and by this mean the particles of tobacco which would interfere with the proper action of the apronrolls will be discharged at one side of the machine. I

To the rocking shaft A are secured the parallel slide-harsh B, which serve to guide the sliding head 0 of the receiving-chamber N, which is adapted for receiving the filler and transporting the same to the bindingrolls a a a a The lower side of the chamber N is formed by the loosely-connected plate E, which is secured to the sliding head 0 by means of the flat spring G. (Shown enlarged in Fig. 12.)

The rocking shaft A is perforated at b to receive the rod 0, attached to the forcer d, which is frictionally held in the sliding head C, and upon the outer end of the rod 0 is placed the guide-roll f. The sliding head 0 is held loosely between the slide-bars B B, so that, upon the downward or outward movement of the rod 0, the friction between the sides of the forcer d and the sliding head 0 will cause the movement of the said slide, with the forcer, until the stop-guides g g at each side of the sliding head strike against the stop-screws h h, which serve to prevent the further outward movement of the sliding head, after which the forcer will be caused to move outward in the slide C.

The rocking shaft A is operated for the purpose of moving the receiving-chamber N from its receiving position, as shown in Fig. '7, to its delivering position between the rolls of the binding mechanism, as shown in Fig.

8, by means of the gear y upon the rocking shaft A, segmentgear 00, loosely arranged upon the rocking shaft to, and having an arm Z, connecting-rod m, and bellcrank lever 01, loosely held upon the rod .9, and which is operated by means of the cam R upon the shaft 15.

The sliding head S is operated from the shaft 0 by means of a bell-crank lever 0, loosely held upon a fixed rod 19, connecting-rod q, bell-crank r, loosely held upon the fixed rod. 8, connecting-rod u, arm 11, shaft to, segmentgear T, and rack T, and the sliding head S is provided with an attached curvedguide U, adapt-ed to suitably control the movement of the forcer d, and from an arm V, extending fromt-he shaft w, connection is made by the rod W to the arm X, secured to the rocking shaft Y, from which is projected the pendent forked arm Z, which is adapted to receive the cylindrical bars or wires 6, (shown in Fig. 3,) the chamber N being in the position shown in Figs. 2 and 7, in which position the movement of the shaft Y and arm Z in either direction will impart a corresponding movement to the sliding head 0.

The upper rolls a a are made to open and close to receive the filler and to roll on the binder, as in machines heretofore constructed, and below the lower rolls a a and in the direction of their axes, I arrange the continuously-driven belt V, which at its delivering end passes around the flanged pulley W, and the belt V will serve to deliver the bunch from the binding-machine rolls to the table X.

Upon the driving-shaft Y, Fig. 10, is placed the clutch Z, operated by means of the lever t, which is pivoted'at' U to the frame of the machine, and the outer end of the lever is held in a fixed slotted arm n, at the inner side of which is pivoted the slotted cam 20, from which connection is made to the pedal 00 by means of the connecting-rody in such a manner that the pressure of the foot upon the pedal-bar x will cause the engagement of the clutch Z and the consequent revolution of the working parts of the machine, and in order to effect this object I make the pedal 00 and arms j 7' of light material, so that the weight of the slotted cam 20, connecting-rod y, and arm k attached to the pivot-shaft m will serve to cause the disengagement of the clutch and the consequent stopping of the machine; or, if preferred, a suitably-arranged spring may be employed to counterbalance the pedal, and thus effect the sure disengagement of the clutch upon the removal of the foot of the operator from the pedal :13.

In operating the machine the loose tobacco is to be first placed upon the apron'B to a 7 the apron B will cause the loose tobacco to which will cause the loose tobacco to be forced between the surface of the spur-roll K and the plate J and onto the upper surface of the apron E, passing thence forward with the intermittent movement of the apron E and between the intermittingly-n1ovin g aprons E and H, the adjacent surfaces of which converge in a forward direction,by which means the tobacco passing between the two aprons E and H will become compressed into a compact sheet between the end rolls F and I, and upon the proper elevation of the knife M by the continued action of the machine the forward end of the sheet of tobacco L will pass forward into the filler-receiving chamber N, and upon the succeeding movement of the cam Q the knife M will separate the filler in the chamber N from the incoming sheet, and thereafter the continued movement of the machine will first cause the backward movement of the arm Z, thus causing the simultaneous backward movement of the sliding head 0' and chamber N, by which means the springplate E, which forms the lower side of the chamber N,will be brought out of the groove. t in the stop-guide S, after which a downward angular movement will be imparted to the sliding head 0, the initial movement of which will allow the spring-plate E to clasp and securely hold the tiller from dropping out of the chamber N when the chamber is held in a downward position, and the angular movement wi l be continued until the chamber N has been brought to a point immediately over the opening between the upper rolls a (1 which at this time will have become separated from each other, as shown in Fig. 8, and immediately upon the arrival of the chamber N, with its inclosed fillers, to the above position a downward movement will be imparted to the forcer d by means of the downward movement of the sliding head S, and thereupon the friction between the sides of the plunger d and the inclosing slide 0 will serve to impart a corresponding downward movement to the slide (1" and its filler-chamber N,until a point is reached between the two upper rolls a a and at this point the sliding head 0 and chamber N will be brought to rest by means of the stops g h, after which the forcer d will continue its downward movement until the filler has been forced entirely from the chamber N and deposited between the binding-rolls in the proper condition for rolling the binder thereon, after which, upon separation of the lower rolls a (L as in ordinary cigar-machines, the bound bunch will drop from the rolls to the carrying-belt V, the continued movement of Which will cause the bunch to be deposited upon the table X, from which it may be taken and placed in the ordinary mold preparatory to receiving the final wrapper. Upon the retrograde upward movement of the forcer' d the friction between the forcer and the sliding head 0 will serve to impart a sim ultaneous upward movement to the sliding head 0 until the upward limit of the movement of the sliding head hasbeen reached, after which the continued movement of the sliding head S will serve to draw the forcer back within the-sliding head 0, so that the face of the forcer will thereafter form the rear of the chamber N. The sliding head 0 will now be made to move angularly with the rocking shaft A along the cylindrica'lly-curved plate M until it reaches a horizontal position, as shown in Fig. 7, the springpl'ate E bringing up against the projecting lip s of the stop-guide S, arranged at opposite sides of the throat-opening r through which the sheet of tobacco passes to the receivingchamber N, and the rods 6 will pass into the notches at the ends of the forked arms Z upon the shaft Y. The spring-plate E will then be held back at the extreme of the angular movement of the sliding head 0, and by this means the chamber N- will become enlarged in a vertical direction, so that the incoming sheet of fillers will not encounter resistance from either the top or bottom plates of the chamber N, and at the same time the filler will be firmly held by means of the resilience of the spring G of the plate E, when the slidinghead C s withdrawn from the stop-guide S. Upon the arrival of the sliding head 0 at the horizontal position shown in Fig. 7 the shaft u; will be moved by means of the cam P upon the shaft 0, and by means of the arm V, connecting-rod W, and arm X the forked arm will be brought forward, thus forcing the sliding head 0 and receiving-chamber N into, close proximity to the throat r through which the tobacco passes in its entrance to the receiving-chamber, the edge of the spring-plate E passing into the holding-groove t of the step.-

guide S, as shown in Fig. 12, by means of which the spring-plate will be supported at the downward stroke of the knife M when separating the incoming filler from the sheet at the throat-opening 4' and the operation of receiving the filler and depositing thesame between the binding-rolls maybe continued as long as tobacco is being fed upon the apron B and the foot of the operator is held-upon the pedal 00, and in case of any miss or accident in the working of the machine the machine may be instantly stopped by the proper elevation of the foot of the operator. V
